About this spot
Case Falls is a real, well-documented 25-foot dammed cascade on Birch Mountain Brook in Manchester's Highland Park / Case Mountain area, with free parking on Spring St. and a short easy walk to the base. Historic mill-dam site. Both dedicated waterfall guides consulted rate swimming here as not possible or prohibited, and no cliff-jumping trip reports or videos were found — treat as a sightseeing stop, not a confirmed jump spot.
Safety first. Cliff jumping is inherently dangerous and can cause serious injury or death. Conditions — water depth, submerged hazards, and access — change constantly. CliffScout is community-sourced reference information, not a guarantee a spot is safe. Always assess the conditions yourself before jumping, and never jump where you're unsure. You assume all risk.
